It was fantastic, thank you for creating and keeping this wonderful theme always updated and improving every day. So I would like to put one more opinion, maybe in its next update could develop the same theme with compatibility to machines that have weaker hardware, so they can also run the smooth theme free of crashes. But so far my opinion for my machine works very well in every way.
Thank you for the comments. I know Arcadeflow is very demanding, and in the past all the tests we did on the forum to adapt it to lower spec machines like the Pi were unsuccessful. There are a couple of things that make low specs machines struggle: the number of (nested) surfaces used by the thumbnail grid, and the number of GLSL shaders and effects used in Arcadeflow. While I can strip back GLSL effects somehow, and even reduce the surfaces, that would change a lot the look of the theme. I'm wondering if the new Pi4 has enough power to run AF, but I don't have a Pi myself to test.
There are some settings in the layout that can be used to disable some effects and hopefully improve performance, but the surface issues still remains.
I've been thinking of a way to streamline the layout for some time, one of the options is, instead of using surfaces for each tile, to use a single surface as big as the screen and apply dynamic shadows to that, but I fear that would be a heavy GLSL shader for lower spec GPUs
